    摘要： A method and image made by the method is disclosed wherein non-spherical magnetically alignable optical pigment flakes in transparent carrier are applied to a substrate and are aligned by applying a magnetic field to the substrate. The pigment flakes align along magnetic field lines and a tool for impressing or scribing the flakes is applied to a sub-region of the substrate to realign or remove flakes from a desired region. For example a scribing tool can be used to scribe a signature or other marks within the magnetically aligned flakes. The flakes are then cured and the image is preserved which has optical and tactile features.

    摘要： Opaque flakes, such as pigment or bright flakes used in paints and inks, have a selected shape and/or other indicia to provide a covert security feature to an object. Shaped opaque covert flakes are not readily detectable by causal observation, but in some embodiments are easily seen at 50× magnification. In manufacturing the flakes a sheet of embossed frames are provided having embossed symbols or indicia within. Upon removing a coating from the embossed sheet the coating material tends to break along frame lines or grooves and the resulting flakes are substantially uniform in size. In order to have the flakes break along frame lines or grooves more readily than along the embossing or grooves defining indicia within a frame, the frames are provided with a deeper groove than indicia grooves. As well a groove having a different shaped profile conducive to breakage can be used for the frame grooves whereas a groove having a profile less conducive to breakage can be used to form the indicia grooves. We have found that the flakes can be further protected from breakage by coating them in a protective coating. This coating may have other features which makes the logo more visible.

    摘要翻译： 不透明的薄片，例如在油漆和油墨中使用的颜料或亮片，具有选定的形状和/或其他标记，以向对象提供隐蔽的安全特征。 通过因果观察不能容易地检测到形状不透明的隐形薄片，但是在一些实施例中，在50倍放大倍数下容易看出。 在制造薄片时，设置有压花框架，其中具有压花符号或标记。 在从压花片去除涂层时，涂层材料倾向于沿着框线或凹槽而断裂，并且所得到的薄片的尺寸基本上是均匀的。 为了使片沿着框架线或槽更容易地沿着在框架内限定标记的压印或凹槽而断裂，框架设置有比标记凹槽更深的凹槽。 同样，具有有利于断裂的不同形状轮廓的槽也可以用于框架槽，而具有不利于断裂的轮廓的槽可用于形成标记槽。 我们已经发现，通过将薄片涂在保护涂层中，可以进一步保护薄片不被破坏。 该涂层可能具有其他特征，使徽标更加可见。

    摘要： An optical structure is disclosed which includes a light transmissive substrate having a surface relief pattern applied thereon, such as a hologram. One or more layers can be patterned corresponding to materials playing the role of absorbers or reflectors on a Fabry-Perot type of optical structure. These materials are applied over portions of the surface relief pattern so as to form alphanumeric characters, bars codes, or pictorial or graphical designs. Additional layers may be applied to the patterned layer of the reflective or absorber materials and exposed portions of the surface relief pattern in order to provide desirable optical effects to the exposed portions of the surface relief pattern. In some embodiments, the optically active coating is a color shifting thin film, or contains color shifting flakes based on Fabry Perot designs. Optionally, the material of the optically active coating is either index matched or not index matched to the light transmissive substrate in order to optically erase or enhance the effect of the surface relief pattern in the portions of the surface relief pattern not covered by the reflective or absorber materials.

    摘要： A printed image is disclosed wherein the image may be in the form of an array of magnetically aligned platelets or flakes that may by uniform in shape and size and wherein the flakes are arranged in a particularly manner to form optically illusive images useful as security devices, or useful in beam steering applications. In one embodiment of this invention printed array is disclosed a plurality of concentric rings of magnetically aligned platelets disposed upon a substrate in the form of a Fresnel structure, preferably a Fresnel reflector. Advantageously, since the magnetic field can be controlled with respect to strength and direction, one can easily design a field that will correct for spherical aberration that would otherwise be present in a typical Fresnel reflector. In other embodiments of the invention optically illusive images of funnels, domes and cones are printed.
